Method for cultivating worm grass in culture medium by solidifying nutrient solution by using water-retaining agent

Abstract

The invention relates to the field of a new worm grass cultivating technology and especially relates to a method for cultivating worm grass in a culture medium by solidifying a nutrient solution by using a water-retaining agent. The method comprises the following steps: firstly, preparing the nutrient solution with rich and balanced nutrition; fully absorbing and solidifying the nutrient solutionby using the water-retaining agent with water absorbency being above 200 times and grains being 100-120 meshes, thereby forming granular solid nutrient solution; taking the solid nutrient solution asa main raw material for preparing grass-growing culture medium; placing the grass-growing culture medium into a cultivation box, performing conventional sterilization, and then accessing a liquid worm grass strain; and managing conventionally till growing the grass. According to the method provided by the invention, season limitation, expensive silkworm chrysalis living organisms and raw materials, such as rice, wheat, corn, and the like, which are required by traditional worm grass production are eliminated; more than 200kg of raw materials are replaced by only 1kg water-retaining agent; andthe traditional heavy work, such as carrying and dosing the raw materials, and the like, is also omitted.

Description

technical field [0001] The invention relates to a new technology field of Cordyceps cultivation, in particular to a method for cultivating Cordyceps by using a water-retaining agent to solidify a nutrient solution as a culture medium. technical background [0002] Natural Cordyceps sinensis is a traditional precious nourishing Chinese herbal medicine, and it is listed as the three major nourishing products together with natural ginseng and deer antler. It has mild medicinal properties, can be eaten all year round, and has wider medicinal value than other types of tonics. Natural Cordyceps sinensis mainly grows in high-altitude and alpine regions, and the composition of the growing environment is very harsh and complex. In addition, people's increasing demand for Cordyceps and unreasonable mining have resulted in the gradual reduction of natural Cordyceps natural resources. In order to solve the shortage of natural Cordyceps sinensis, the market demand can only be met throug...

AI Technical Summary

Problems solved by technology

The growth cycle of Cordyceps is nearly two months, which will inevitably consume a lot of energy and increase the cost of production invisibly. In addition, the current price of live silkworm chrysalis cocoons with cocoons still needs 36-40 yuan / kg. Excluding cocoons, silkworm chrysalis Fewer live worms, higher cost

Therefore, the use of silkworm chrysalis live insects to produce Cordyceps fruiting bodies is not only limited by the production season, but also has a high cost of use.
